There is nevertheless a certain respect, a general duty
to humanity, not only to beasts that have life and sense,
but even to trees and plants. We owe justice to men, and
graciousness and benignity to other creatures ... there
is a certain commerce and mutual obligation betwixt them and us.
Michel de Montaigne
Life just seems so full of connections. Most of the time
we don't even pay attention to the depth of life.
We only see flat surfaces.
